I used to have an O3DS (unhacked) and then I bought a N3DS, I did system transfer from the O to the N. The n3ds is the one I got banned. I did the movable and LFCS thing and I can play online again, I also used the mega mew luma patch to "unlink" my nnid just in case... mainly because I have a lot of wiiu games in that account... not so many in 3ds though.
my question is, should I stay like this? Can I get banned again? what if I remove the luma patch and just stick to the movable-lfcs system transfer trick? Also... The o3ds i previously owned is now my brother's (still unhacked), can his 3ds get banned too?
